Description
Technical Field
The invention relates to the technical field of ice-based profilers, in particular to a releasing device of an ice-based profiler and a data acquisition system.
Background
North has a significant impact on global climate change, but conventional profilers cannot operate in the north because north is covered by sea ice throughout the year. The intrinsic mechanism of influencing global climate in arctic is limited by the observation data which are less and can not be determined all the time. Many organizations are working to develop equipment for long term observation of the arctic, and a series of ice-based profilers have been used for arctic observation under years of effort.
As global climate warms, arctic sea ice is younger and younger, melting faster and faster. Existing ice-based profilers are placed on years of ice, which, on the one hand, can only bear the weight of the entire system for years, and on the other hand, the rapid ablation of sea ice causes surface floats on thin ice to quickly lose the support of the sea ice, which is flushed by strong cross flow towards shallow water, resulting in grounding. Once stranded, the ice-based profiler may not function properly, and a serious one may also result in the loss of the ice-based profiler. This results in fewer and fewer ice layers suitable for laying ice-based profilers, greatly limiting the scope of application of ice-based profilers. In addition, due to the complexity of the marine environment, ice-based profilers are very susceptible to unforeseen anomalies such as entanglement, which can lead to paralysis of the entire system.
It can be seen that the scope of application of ice-based profilers is limited for various reasons, the lifetime of the ice-based profiler is shortened, and the deployment of the ice-based profiler is not affordable compared to its high cost.

Detailed Description
The following further describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 and 2, an embodiment of the present invention provides an ice-based profiler release device, which may include: the device comprises a bracket 12 and at least two clamping pieces, wherein the bracket is fixed on the ice-based profiler 4 after the clamping pieces are connected end to end through electromagnetic unlocking bolts 22; the electromagnetic unlocking bolt 22 comprises a shell, a connecting piece, a locking piece and a driving piece 30, wherein one end of the connecting piece penetrates through one clamping piece and then is fixed on the other connected clamping piece, the other end of the connecting piece extends into the shell and is provided with a counter bore along the axial direction and a through hole along the radial direction, the inner wall of the shell is provided with a clamping groove, and the electromagnetic unlocking bolt 22 can be switched between two working positions for locking and releasing and is configured as follows: in the locking working position, one end of the driving piece extends into the counter bore and presses the locking piece between the through hole and the clamping groove; and in the release working position, the driving piece is retracted, and the locking piece is not positioned between the through hole and the clamping groove, so that the shell and the connecting piece can be separated.
In view of the above embodiments, the present application provides an ice-based profiler release device, in order to implement a release function of a bracket and an ice-based profiler, an electromagnetic unlocking bolt is switchable between two working positions, namely, a locking position and a releasing position, and is configured to: in the locking working position, one end of the driving piece extends into the counter bore and presses the locking piece between the through hole and the clamping groove; and in the release working position, the driving piece is retracted, and the locking piece is not positioned between the through hole and the clamping groove, so that the shell and the connecting piece can be separated. When the locking device needs to be released, the control system sends an instruction to enable the electromagnetic unlocking bolt to be located at a releasing working position, so that the pre-tightening force of the elastic wrapping belt is released, and the locking of the bracket and the ice-based profiler is released. Therefore, the whole operation can be ensured to be safe and reliable when the system works normally; when abnormal conditions occur, the ice-based profiler can be released to work independently, and the problems in the prior art are better solved: the ice-based profiler is inseparable from its data acquisition system, and the data acquisition system once stranded, or twine with the ice-based profiler, or the communication interrupt that other reasons caused, all can lead to the problem of whole system paralysis. The ice-based profiler has the advantages of wide application range, high survival rate, low data cost, simple structure, stable operation and high reliability.
In the embodiment of the invention, in order to separate the ice-based profiler 4 from the data acquisition system, the plastic-coated steel cable 2 of the data acquisition system cannot directly pass through the ice-based profiler 4, and the ice-based profiler 4 needs to adopt a buoyancy-adjusting driving mode. Therefore, the ice-based profiler release device designed by the invention is additionally provided with a bracket 12, and the bracket 12 is provided with a guide roller 13 so as to facilitate the vertical movement of the bracket along the plastic-coated steel cable 2 with the ice-based profiler 4, thereby acquiring profile data.
In the embodiment of the invention, the clamping piece comprises an elastic wrapping tape 15 and a clamping block 14, and in order to realize the connection and fastening of the bracket 12 and the ice-based profiler 4, the clamping block 14 is installed between the elastic wrapping tape 15 and the ice-based profiler, so that the pre-tightening force of the elastic wrapping tape 15 is applied to the ice-based profiler 4 through the clamping block 14, and the locking function is realized. Circumferential pretightening force is applied to the clamping block 14 through the two sections of elastic wrapping belts 15, and the elastic force generated by deformation of the elastic wrapping belts 15 is balanced through the electromagnetic unlocking bolts 22 at the two ends, so that the ice-based profiler 4 can be firmly fixed on the bracket 12.
In the embodiment of the present invention, a separation spring 16 is further disposed between the two connected clamping members to ensure that the electromagnetic unlocking bolt 22 has sufficient separation force between the housing and the connecting member to achieve separation. An outward pushing spring 11 is arranged between the bracket and the ice-based profiler, and the ice-based profiler 4 is ejected out by the outward pushing spring, so that the rapidness and the reliability of the releasing process are ensured, and the long separating process and other unexpected situations are avoided.
In the embodiment of the present invention, an electric solenoid 27 is further included, and the other end of the driving member 30 extends into the electric solenoid 27, so that the electric solenoid 21 can apply sufficient driving force to the driving member 30.
In the embodiment of the present invention, the electric solenoid 27 and the driving member 30 are provided with a spring 28 to ensure that the locking member can be tightly pressed between the through hole and the locking groove when the driving member 30 is in the locking working position, so as to prevent the locking member from being accidentally withdrawn.
In the embodiment of the present invention, the housing includes a top cover 23 and a threaded sleeve 24 fixed on the top cover, so as to facilitate the assembly of the electric solenoid 27 into the threaded sleeve of the electromagnetic unlocking bolt 22.
In the embodiment of the invention, the intelligent control system further comprises a control cabin 19 for installing a control unit, an inductive coupling module 18 and an underwater WIFI module 20 for wireless communication, wherein the electromagnetic unlocking bolt 22, the inductive coupling module 18 and the underwater WIFI module 20 are respectively connected to the control cabin 19 through watertight connectors. Therefore, the control unit is ensured not to contact with seawater and can bear the high pressure of the seawater, and the control on the operation and communication of the whole system is realized.
In the embodiment of the invention, a battery compartment 17 for installing a power supply is further included, and the control compartment 19 is connected to the battery compartment 17 through a watertight connector so as to obtain electric energy necessary for the operation of the system.
To ensure that the ice-based profiler 4 can continue to operate after release, the carrier 12, and all devices outside the ice-based profiler 4 attached to the carrier 12, are entirely in a zero-buoyancy state under the buoyancy of the buoyant material. Thus, the ice-based profiler need not provide buoyancy to other devices, and may continue to operate upon adjusting its own buoyancy after release.
As shown in fig. 3, an embodiment of the present invention further provides a data acquisition system, including: the ice-based profiler release device comprises a surface floating body 1, a plastic-coated steel cable 2, a ballast block 3, an ice-based profiler 4 and the ice-based profiler release device as claimed in claim 1, wherein one end of the plastic-coated steel cable 2 is connected with the surface floating body 1, the other end of the plastic-coated steel cable 2 is connected with the ballast block 3, the ice-based profiler 4 is installed on the ice-based profiler release device, and the ice-based profiler release device is sleeved on the plastic-coated steel cable 2 and can slide along the plastic-coated steel cable 2.
This not only allows the profiler to collect data for the vertical profile, but also to transmit these data back to the laboratory in real time.
The working process of the embodiment of the invention is as follows: firstly, two sections of elastic wrapping belts 15 and clamping blocks 14 are used for compressing the ice-based profiler 4 to push outward the springs 11 and then are fixed on the bracket 12, two ends of the elastic wrapping belts 15 are used for compressing the separation springs 16 and then are connected and fastened by electromagnetic unlocking bolts 22, and the shell and the connecting pieces 25 are respectively positioned on two sides of the two sections of elastic wrapping belts. In the locked state, the driver 30 of the electromagnetic unlocking bolt 22 is in abutment with the catch ball 29 under the action of the spring 28, so that the catch ball 29 is pressed between the through hole of the housing and the catch groove, thereby achieving axial locking of the housing and the connecting piece 25. At this point, the elastic wrapping belt 15 applies elastic pre-tightening force to the clamping block 14, so that circumferential and axial locking of the ice-based profiler is realized; the two ends of the elastic wrapping tape 15 balance the pre-tightening force of the elastic wrapping tape 15 and the separation spring 16 by using the electromagnetic unlocking bolt 22, and a lead 31 of the electromagnetic unlocking bolt 22 is connected to the control cabin 19 through a watertight connector.
When the system normally works, the ice-based profiler 4 and the bracket 12 are locked together, data are measured while vertically moving along the plastic coated steel cable 2, the collected data are wirelessly connected with the ice-based profiler releasing device through the underwater WIFI module 20, the inductive coupling module 18 is connected with the underwater WIFI module 20 and used for receiving the data transmitted back by the underwater WIFI module 20 and transmitting the data back to the surface floating body 1 through inductive coupling, and the surface floating body 1 is communicated with the ground control center through iridium satellite.
During operation, the control system detects the operating state of the ice-based profiler according to the mechanism of FIG. 4, wherein depth data is obtained from the ice-based profiler and tilt angle information is obtained from the inclinometer. When an abnormal condition is detected, a voltage signal is given to the solenoid 27 of the electromagnetic unlocking bolt 22, the solenoid generates suction force on the driving member 30, overcomes the elastic force of the spring 28 and the extrusion force of the latching member ball 29, so that the groove of the driving member 30 is aligned with the latching member ball 29, and the latching member ball 29 falls into the channel of the connecting member 25 under the action of radial force, thereby unlocking the housing and the connecting member 25. Furthermore, under the pretightening force of the elastic belting 15 and the separation spring 16, the shell is separated from the connecting piece 25, the elastic belting 15 drives the clamping block 14 to be separated from the ice-based profiler 4 under the pretightening force, and the unlocking of the ice-based profiler 4 is realized. Finally, the ice-based profiler 4 is ejected out under the action of the outward pushing spring 11, completing the release. The released ice-based profiler continues to work by adjusting the buoyancy of the profiler, floats out of the water surface when running to an open water area, and is communicated with a ground control center through the iridium satellite.
The application provides an ice-based profiler release device and a data acquisition system, which can ensure the safe and reliable overall operation when the system works normally; the ice-based profiler can be released to work independently in the event of an abnormal condition. The problems existing in the prior art are better solved: the ice-based profiler is inseparable from its data acquisition system, and the data acquisition system once stranded, or twine with the ice-based profiler, or the communication interrupt that other reasons caused, all can lead to the problem of whole system paralysis. The ice-based profiler has the advantages of wide application range, high survival rate, low data cost, simple structure, stable operation and high reliability.
